Abstract
This paper focuses on an efficient method for three-dimensional finite element models with respect to computational time and accuracy of the solution. In the finite element method, the accuracy does not only depend on the level of abstraction from a real physical problem, but is also restricted by parameter and model uncertainties, including material, geometry, boundary conditions and mesh construction. In order to ensure an acceptable solution for a particular application, it is necessary to identify and quantify these uncertainties by performing a sensitivity analysis on the solution. In this work, an experimental modal analysis (EMA) was performed on monolithic and assembled structures to evaluate the results from the finite element models, concerning parameter and model uncertainties.
